給水口、金具取付け孔等の孔を開けた製品が多い。(B) Conventional technology Ceramics, especially sanitary ceramics such as toilets, washbasins, counters with washbasins, accessories, etc.
Many products have holes such as water inlets and fitting mounting holes.
この様な開孔部を持つ陶磁器類を鋳込成形する方法の
一つとして、泥漿鋳込方法がある。As one of the methods for casting ceramics having such openings, there is a slurry casting method.
同鋳込方法を、製品が洗面ボウルの場合を参照して説

ｄから成形品としての洗面ボウルの脱型搬出を行い、そ
の後、成形品を養生することによって行われる。The casting method will be described with reference to the case where the product is a washbasin. As shown in FIGS. 3 and 4, first, a mold material layer a forming a molding surface and a mold material supporting the same mold material layer a The upper mold c and the lower mold d having the two-layer structure composed of the backup layer b are assembled and pressed to form a molding pouring space e, and a slurry is injected into the molding pouring space e and pressurized. , The above c
And only the moisture in the slurry is permeated and discharged by the mold layer a of the lower mold d, and after completion of the predetermined inking, the excess slurry is discharged. After a predetermined time, the upper mold c is separated from the lower mold d. This is carried out by removing the wash bowl as a molded product from the mold d and then curing the molded product.
しかして、洗面ボウルは、後部平坦部に、通常、水栓
金具等を取付けるための取付孔を設ける必要があるが、
かかる取付孔を設けるため、第４図に示すように、上型
ｃの成形面に、非吸水性の孔成形用型ｆを接着又は埋め
込み等の方法で取り付けている。Thus, the wash bowl usually needs to be provided with a mounting hole for mounting a faucet fitting or the like on the rear flat portion.
In order to provide such mounting holes, as shown in FIG. 4, a non-water-absorbing hole forming die f is mounted on the forming surface of the upper die c by a method such as bonding or embedding.
ところで、上型ｃと下型ｄを型組みしてプレスした場
合（プレス装置は図示せず）、孔成形用型ｆの先端は、
下型ｄに密接している事が必要である。By the way, when the upper die c and the lower die d are assembled and pressed (the press device is not shown), the tip of the hole forming die f is
It is necessary to be close to the lower mold d.
というのは、孔成形用型ｆの長さL1が、上型ｃと下型
ｄの成形面間に形成される成形鋳込空間ｅの長さL2より

と、上型ｃと下型ｄを型組みしてプレスした場合、孔成
形用型ｆの先端は、下型ｄの型材層ａにぶつかって、同
型材層ａ、下型ｄを破損してしまうことになるからであ
る。That is, when the length L1 of the hole forming die f is shorter than the length L2 of the molding pouring space e formed between the molding surfaces of the upper die c and the lower die d, the slurry is deposited on this part. As a result, the hole is completely closed or half-opened, and the purpose of complete hole opening cannot be achieved. On the other hand, the length L1 of the hole forming die f is formed by the upper die c and the lower die d. If the length of the casting space e is longer than the length L2, when the upper die c and the lower die d are assembled and pressed, the tip of the hole forming die f collides with the die material layer a of the lower die d. This is because the mold material layer a and the lower mold d will be damaged.
かかる下型ｄの破損を防ぐため、ゴム等の弾力性のあ
る材質によって孔成形用型ｆを形成する場合もあるが、
かかる孔成形用型ｆは、圧縮されると径が変化してしま
い、成形品に孔を正確に設けることができなくなる。In order to prevent the lower mold d from being damaged, the hole forming mold f may be formed of an elastic material such as rubber.
The diameter of the hole forming mold f changes when it is compressed, and it becomes impossible to accurately form holes in a molded product.
従って、孔成形用型ｆの長さL1は、上型ｃと下型ｄで
形成される成形鋳込空間ｅの長さL2に合わせて正確に決
めなければならない。Therefore, the length L1 of the hole forming die f must be accurately determined in accordance with the length L2 of the molding pouring space e formed by the upper die c and the lower die d.
（ハ）発明が解決しようとする課題 ところが、第４図に示す形成鋳込空間ｅの長さL2は、

に正確に密接させる事は難しいため、孔成形用型ｆの長
さL1の決定は従来極めて困難であった。(C) Problems to be Solved by the Invention However, the length L2 of the casting space e shown in FIG.
It is fluid due to the degree of tightening by the pressing device, the variation in the seal thickness of the mold mating surface g, the wear of the mold material layer a, etc. Since it is difficult to bring them into close contact, it has conventionally been extremely difficult to determine the length L1 of the hole forming die f.
また、造型時に孔成形用型ｆを上型ｃに固定するため
の両面テープや接着材等の厚み、ケースから離型させる
ためのワックス代等の要因により、上型ｃと下型ｄで形
成される成形鋳込空間ｅの長さL2に密接した孔成形用型
ｆの製作自体も困難であった。Also, the upper mold c and the lower mold d are formed due to factors such as the thickness of a double-sided tape and an adhesive material for fixing the hole forming mold f to the upper mold c during molding, and a wax allowance for releasing the mold from the case. Also, it was difficult to manufacture the hole forming die f close to the length L2 of the formed casting space e.

止することができる。In the present invention, since the hole forming die length adjusting device for adjusting the length of the hole forming die in the molding pouring space is attached to one of the opposing dies, the lengths of the hole forming dies are opposed to each other. When assembling the dies, it is possible to accurately adjust the tip of the hole forming die to be in close contact with one of the opposing dies, preventing damage to the opposing dies and poor formation of completely closed or semi-open holes. It can be completely prevented.
従って、余分な泥漿着肉の除去作業をカットすること
ができ、着肉の除去作業忘れによる不良品発生の撲滅が
できる。Therefore, it is possible to cut off the work of removing the excess sludge deposit, and it is possible to eliminate the occurrence of defective products due to forgetting to remove the deposit.
